Shortly after the Second World War, several small private airlines were formed in Malta. Amongst these were The Malta Instone Airline, BAS (Malta) Ltd, and Malta Airlines. In 1947 the former two companies merged to form Air Malta Ltd in fierce competition with the latter.
Eventually in 1951 Malta Airlines absorbed the operations of Air Malta Ltd and continued operating through an agreement with BEA until 1973. The owners of Air Malta Ltd used their real estate, staff and equipment to set up a ground handling company called MAS, Malta Aviation Services. To find out more about this airline you can find it on wikipedia site.
